My invention relates to cooling systems for internal combustion engines, having more particular reference to an improved radiator system by which the cooling liquid flows directly for simultaneous passage from several areas within the jacket to the radiator, and including an im- 4 Claims. (oi. lax-41.23)

Fig. -3 shows a plan view of a fragment of cylinder head with 'hose casting andconnecting proved-lining for the system adapted to conduct the heat from the walls of the jacket and passages more rapidly, and to retard scaling.

In the art to which the invention relates it has been proposed to provide a cooling system for internal combustion engines in which the liquid is conducted from cooling jackets for the cylinders by a series of pipes, one for each cylinder area, designed to promote a more uniform cooling of the engine.

The present invention contemplates improvements in cooling systems of this character by provision of an improved jacket for the engine, and includin an improved arrangement of the liquid passages leading to a, common source of supply, and further to provide a lining for the Jacket and passages adapted to promote the flow of the cooling liquid.

One of the objects of the invention is accord ingly to provide an improved jacket for internal combustion engines with individual cooling passages for each cylinder area and includin spaced partitions or walls forming cooling compartments.

A further object of the invention is to provide an improved arrangement of pipes providing passages for the liquid to and from the radiator, and adapted for use with the present type of engine employing a single jacket by connection therewith at intervals to permit passage of the liquid from several areas in the jacket to the radiator.

A still further object of the invention is to provide in an engine cooling system a lining for the jackets and passages of the system adapted to facilitate flow of liquid through the system.

Other features and advantages of the invention will become apparent by reference to the accompanying description taken in conjunction with the drawings wherein lik characters of reference indicate like parts throughout the several views'and wherein- Fig. 1 is a side view partly broken away showing an engine block with individual passages leading to cooling jackets for the cylinders.

Fig. 2 shows a side view of the engine head and pipe leading from the radiator, in which the head is formed with spaced partitions between engine units.

plate,-and pipes leading to and from the plate and casting.

Fig. 4 15a side view-showing the hose casting and connecting plate that provides the connection between the pipes leading from the engine head and the pipe for connection to the radiator. Having reference to the drawings, I indicates vthe'cylinder headof an engine with cooling pipe 2.1eading by a series of branch pipes 3, 4 and 5 to individual jackets in the cylinder head by which the warm liquid may be fed directly and simultaneously from each cooling jacket to the radiator. The pipe 2 leads, as in Figure 2, to a radiator 6 that includes the usual hose connection I9.

In Figure 2 I provide the cylinder head with sets of spaced partitions I and 8 definin an area 9 between each set to form liquid cooling compartments, which compartments connect directly with the pipe 2. leading to the radiator.

To improve the flow of liquid from the radiator, individual pipes connecting to each jacket or cooling area in the cylinder head may be connected direct to the radiator. In Figures 3 and 4 is shown such an arrangement in which a plate I0 is provided having openings at H, I 2, i 3 and N, that communicate respectively through flexible pipes l5, "5, I1 and IS with .the cooling jacket in the cylinder head. To the plate In would be attached a radiator hose casting providing a plate 20 mating with the plate It, secured thereto by bolts 22, and with a pipe 2| for connection to the radiator, the whole being secured to the cylinder head. The casting 20, plate 10 and pipes l5, l8, l1 and i8, provide individual communicating means to the several jacket arts or cooling areas of the engine head for a more uniform cooling by liquid passing therethrough.

To facilitate passage of the cooling liquid through the system I coat or plate the inner walls of the cooling liquid passages and jacket in the engine block, and the engine head, witha non ferrous. metal, glass or inorganic, mineral substance adapted to conduct or transfer the heat from the walls of the jacket or compartments and liquid passages more rapidly, and to reduce scal- In the use of the device the cooling liquid may circulate directly to individual jackets or areas of the cylinder head from the radiator, or to spaced connections with the single jacket type of cooling system, more particularly where an individual connection of each pipe from the cylinasaaus 3 der head to the radiator is made as in Figure 3. To this is added the coating of the jackets or areas and pipes to promote transfer of heat and reduce scaling.

While I have herein disclosed a preferred embodiment of my invention it is obvious that changes in the construction and arrangement of parts would be permissible, and in so far as such changes come within the spirit and scope of the invention as defined in the appended claims they 10 would be considered a part hereof.
